To all whom/it mag/concern;

Be it known thatLPoRrrnR Comb, in the county-of- Pottawatomie, State Y check-row corn planters, and itVA aims,genl

ofOklahoma, havefinvented certain new and Y useful Improvements yin Check-Row Corn- Planters 5. and I do hereby declareithe fol'- lowing to be a full, clear, and exact description of the invention, such-aswill enable others skilled in the art to .which'it apperl tains to make and use the same; Y y n The present invention has reference to erally, to provide anfexceedingly simple, Aas well as highly efficient machine Qf` that type including dropping y mechanism and mark ing mechanism connected,together for syn chronous action.` Y v l More especially, however,the invention resides in the particularfmeans employed for operating the above-mentionedV mechanisms,

and in the speciicconstruction ofthe marking mechanism, whichlatter includes a longitudinally-slotted rod4 mounted in suchav manner as tobe capable of both vanvr endwise and a swinging movement so timed that the pointed lower end of the rod enters the ground simultaneously with the discharge of the seed fromthedropper` mechanism,r

thus forming a series-of shallow cavities, or

furrows which alineexactly with the points perspective viewof the 'marker-and its (jperatmg mechanism., Eig. is an enlarged* in themain furrows where the seedl falls and thus form guideswfor the deposit;ofseeds in the succeeding furrows.

The invention further residesin the provision of means for effectingv a vertical'adjustment of that portionfofthe frame,which carries the above-mentionedfmechanisms, and of means for throwinglsaid mechanisms into andout of operation, n ,n

TheV invention will be readily understood from a considerationpfthe following detailed description, and its `preferred embodimentv` is illustrated in*V the @accompanying drawings in which like parts or features, as

the case maybe, are designated by .corresponding reference'numerals in the several views.` n n n i Of the said drawings :eFigure l1 is atop plan ,view thereof. Fig. y211s an enlarged perspective viewof the main drive sprocket and the clutch leverqwith it engaged.

s f. y i l ingsi.7 designates,generally, the U-shaped C. Fox,av citi-VV zen of the United; States, ,residingl at Mc-` `:metal frame of the machine the free ends of gwhose arms are pivoted between pairs of ears secured to the rear` face of the front sill 8 to which the tongue 9 is fastened. The frame restscentrally upon the axle 10 and carries a longitudinally-disposed beam 11 which alines with the tongue` 1 n y' Thesill above referred to carries both the dropper and the marking mechanism, the `n' former of which is generally designated by the numerals 12, 12, the hoppers to which said numerals specifically refer being mount- ;ed uponthe sill Stewards the opposite ends thereof, the devices within the hoppers being operativelyy connected with a shaft 18 disi posedlongitudinallyoffsaid sill and journaledin brackets fastened thereto.V To eect its rotation, the shaft` 18 is `provided with a sprocket 19 connected `by a, chain 20 with a l larger sprocket 21 loosely mountedpupon the `axle 10 and having its hub portion formed with-'a clutch face 22 and with a circumscribing series of ratchet teeth 23, the clutch face being adapted for engagement with that of a sleeve 24 keyed upon the axle and provided with a circumscribing groove in which the yoke portion of a lever26 fits comparatively loosely, it being thus possible to throw said shaft into and out of operation according as the sleeve is moved in one direction or the other by the lever. Said lever, moreover, carries a laterally-projecting pawl 27 adapted for engagement with the ratchet teeth 23, so as to permit a rotation ofthe sprocket 21 at la greater rate of speed than that of the axle,

or, in other words, independently thereof, `such rotation being efected merely by a swinging movement of the lever after its pawl hasbeen engaged with the ratchetteeth, the loose lit of the lever yoke in the sleeve groove rendering such movement possible.

The marking mechanism, which, as above Referring more"V particnlarly to the draw-l intermediate its ends with `a longitudinal slot 35 carried by a pair of depending straps 36 secured to the sill.

By reason of this construction, it will be.

apparent that upon the rotation of the crankshafts, the blades will be given both a vertical and a swinging movement, the latter being effected by the pin and slot above referred to. The pointed lower ends of the blades will therefore dig small cavities or furrows in the ground, the several gears carried by the crank-shafts and the shaft 18 being so proportioned that the formation of a cavity is simultaneous with a discharge from the hopper, and such cavity or furrow, moreover, is disposed exactly in alinement with that in the preceding row which has been filled by the seed discharged, and extends parallel with the same.

In order to regulate the depth to which the blade ends penetrate into the ground, means is provided for bodily raising or lowering the sill 8, and to this end the beam ll has pivoted thereto forwardly of the axle a lever 37 pivotally connected by a link 38 with one arm of an angle-lever 39 whose opposite arm is similarly connected by a link 40 with a projecting shoulder ll formed by a block secured centrally to the sill. Movement of the lever in one direction will therefore raise the sill from the ground, and in the other direction will lower the sill, the lever being retained in adjusted position by a dog and 'rack mechanism of any preferred type.

The operation of the machine is thought to be apparent from the foregoing, and further Vdescription thereof is deemed unnecessary beyond tlie statement that the marks of each series `aline exactly with the deposits of seed, and that when one row has been planted, and the machine is turned to plant the succeeding row, the pointed end of one of the blades will descend into the previously formed marks, thus effecting the deposit of seed lat points exactly in line with those in the preceding row. When, however, the blade end, in its descent, fails to strike the previously formed marks, the sprocket 21 is rotated by the pawl-earrying lever 26 until the blade end reaches the desired point,

. whereupon the progress of the machine is continued. The rotation of the axle is effected by means ofthe traction wheels 42 which are carried thereby, the periphery of said wheels being slightly vconcaved, as

, shown.
